Tensile tests were carried out using a large numbers of JIS No. 5 and 13A types specimens of 5052-0 plates 3mm thickness and 7N01-T6 5mm thickness. The specimens in Barba type materials such as 5052-0 alloy frequently fracture near the end of the gage length, but ones in Oliver type materials such as 7N01-T6 rupture near the center of the gage length. The elongation δ0 is almost independent of the fracture position in 5052-0, but decreases in 7N01-T6 as fracture occurs near one end of the gage length. The presumed elongation δ1 were calculated in the method JIS Z 2241 (Method of Tensile Test for Metallic Materials) for the specimens in which fracture occurred near the end of the gage length. δ1 is neary equal to δ0 for the Barba type materials independent of the fracture position, but is larger than δ0 for the Oliver type materials as fracture occurs near one end of the gage length.
